IntroductionEating healthy consists of consuming a balanced diet of fruits, vegetables, whole grains, healthy oils, low fat dairy and lean animal or plant-based proteins. This balance is outlined in the United States Department of Agriculture's healthy foods pyramid. This pyramid acts as a basic guideline to eating in such a way that you promote a healthy body. Of course, this pyramid can be altered to fit your lifestyle (such as that of a vegetarian), but the same principles apply in getting the right mixture of carbohydrates, healthy fats and protein needed for the body to function correctly.
Weight Control
When eating a balanced diet, one of the first ways that your body benefits is through weight control. According to the Centers for Disease Control, in 2006 alone, over 72 million Americans over the age of 20 were considered obese. Obesity is defined as a body mass index (BMI) score of 30 or more. Eating healthy helps prevent obesity in several ways. First, those who eat healthy tend to take in less calories during meals. Second, eating healthy ensures higher amounts of fiber (such as those found in fruits vegetables and whole grains). Fiber gives your body the sensation of feeling fuller longer, which reduces the overall intake of food during the day. Finally, eating healthy influences your metabolism, allowing you to burn more calories each day.
Heart Health
A healthy diet replaces unhealthy fatty foods packed full of LDL (bad) cholesterol with foods that are full of HDL (good) cholesterol (such as olive oil or salmon). High levels of LDL cholesterol in the blood create plaque buildup in the blood vessels. This can lead to arterial hardening and heart disease. HDL cholesterol removes bad cholesterol from the bloodstream to the liver, where it can then be processed and removed from the body. A healthy diet is also high in fiber, which can help control the levels of bad cholesterol in the blood.
Blood Sugar
Eating healthy also benefits your body by helping control your blood sugar levels. This is mostly achieved through eating healthy forms of carbohydrates. Eating foods full of sugar and other unhealthy forms of carbohydrates can quickly cause the levels of blood glucose to rise in your circulatory system. Although your cells need glucose to create energy, too much glucose can result in insulin resistance, known as diabetes. Insulin is an important hormone that unlocks the cell's ability to absorb glucose from the bloodstream. When the cells become resistant, they no longer can absorb the glucose from the blood. This causes the glucose levels to rise above healthy levels in the bloodstream, resulting in serious damage to the blood vessels.
Disease Prevention
Eating healthy also helps the body prevent disease. Healthy foods, especially vegetables, tend to contain higher levels of phytochemicals. Pytochemicals are substances that increase your immune system's ability to fight diseases. Eating healthy also helps prevent conditions that promote disease. For example, according to the Mayo Clinic, by eating less fatty foods and increasing the amount of plant-based foods you consume, you can actually prevent certain cancers. Eating healthy can also help prevent heart disease, diabetes, strokes and even Alzheimer's disease.

Welding galvanized steel is common in the metal fabricating industry. Most welders will at some point in their career perform a weld on galvanized steel and encounter galvanize poisoning or "metal fume fever." Galvanize poisoning is a short-term reaction to overexposure of zinc oxide. Zinc oxide is produced when the steel's galvanized coating is heated and evaporates.
What is Galvanized Steel
Galvanized steel is iron that is coated with zinc. When hot-dipped, the zinc chemically reacts with the base metal to form a corrosion resistant coating. The outer layer of the coating is pure zinc and subsequent layers gradually change in composition until they reach the iron base metal.
Between the zinc outer layer and iron base metal, zinc oxide is present in varying percentages of zinc to iron. The zinc oxide has the same chemical make-up as the white powder used by lifeguards to protect their noses against sunburn.
Signs of Galvanizing During Welding
Proper prep work to remove galvanizing from the weld area will reduce your exposure to zinc oxide fumes, but some galvanize will remain in the weld area. Yellowish-green smoke, white powdery particles floating in the air and white residue around the weld are sure signs that zinc oxide is present while welding.
Exposure to large amounts of the yellowish-green zinc oxide fumes will result in galvanize poisoning, commonly referred to as metal fume fever. The amount of exposure will have a direct effect on the severity of your symptoms.
Symptoms of Galvanize Poisoning (Metal Fume Fever)
Signs of galvanize poisoning are similar to flu symptoms. The onset of metal fume fever begins shortly after the body is exposed to zinc oxide and the symptoms include a slight headache and nausea. With increased exposure, flulike symptoms begin to set in.
Moderate zinc oxide exposure results in chills, shaking, slight fever, vomiting, and cold sweats. When the listed symptoms begin, it is time to stop welding and get fresh air. The symptoms can quickly become debilitating and you may need to go home and let the symptoms subside.
Fatalities have been associated with extreme cases of galvanize poisoning. Therefore when metal fume fever symptoms begin, you should immediately avoid further exposure.
How Long "Metal Fume Fever" Lasts
Metal fume fever is short-lived and the symptoms begin to fade within four hours of exposure and generally completely fade within 24 hours. Extreme cases of overexposure may see metal fume fever symptoms last for as long as 48 hours.
Drinking milk can quicken the recovery process as calcium helps remove the zinc build-up from your body.
There have been studies performed by the Centers for Disease Control (CDC) and the Occupational Safety and Health Administration (OSHA) on the long-term effects of welding galvanized steel. No studies have shown long-term health problems due to continued exposure to zinc oxide fumes or repeated cases of metal fume fever.
Avoiding Overexposure to Galvanize Fumes
Proper ventilation, avoiding direct contact with zinc oxide smoke, and proper pre-welding prep work will reduce the chances of your getting metal fume fever. Experienced welders that have had metal fume fever will tell you that drinking milk before, during and after welding galvanized steel will help eliminate the galvanize poisoning.
There are specialized fresh air welding hoods available for welders who frequently weld galvanized steel.

Garlic has “significant” potential for preventing cardiomyopathy, a form of heart disease that is a leading cause of death in people with diabetes, scientists have concluded in a new study. Their report, which also explains why people with diabetes are at high risk for diabetic cardiomyopathy, appears in ACS’ bi-weeklyJournal of Agricultural and Food Chemistry.
Wei-Wen Kuo and colleagues note that people with diabetes have at least twice the risk of death from heart disease as others, with heart disease accounting for 80 percent of all diabetes-related deaths. They are especially vulnerable to a form of heart disease termed diabetic cardiomyopathy, which inflames and weakens the heart’s muscle tissue. Kuo’s group had hints from past studies that garlic might protect against heart disease in general and also help control the abnormally high blood sugar levels that occur in diabetes. But they realized that few studies had been done specifically on garlic’s effects on diabetic cardiomyopathy.
The scientists fed either garlic oil or corn oil to laboratory rats with diabetes. Animals given garlic oil experienced beneficial changes associated with protection against heart damage. The changes appeared to be associated with the potent antioxidant properties of garlic oil, the scientists say, adding that they identified more than 20 substances in garlic oil that may contribute to the effect. “In conclusion, garlic oil possesses significant potential for protecting hearts from diabetes-induced cardiomyopathy,” the report notes.
